It seems Australian singer/media personality Ricki Lee Coulter will not be baring her bum for Hold Me Tightly shapewear once her contract is up because…

She's just too skinny!

The Australian Idol alum went from a size 14 to a size 8 and no longer has the shape that shapewear represents.

One source reveals:

"(Ricki-Lee) looks incredible and this has nothing to do with that - she just no longer appeals to the customer they (Hold Me Tight) target. One of the poster slogans say 'These curves are a work of art'. Anyone who has seen (Ricki-Lee) lately knows that just isn't so any more."
